I looked into the Carnai, but my dealer was out, and to order one w/ mast stand & shipping was about $1100.
I decided to look into other options. I found that I could get a Karavan KBE-1250-46 which is just a basic bunk trailer with 12" wheels, bunks and winch, and is very well suited for the Wave. I was able to buy it from a local boat dealer for about $650, and then I purchased the catamaran kit directly from the Karavantrailers.com online catalog. I trimmed the crossbeams down (they came 98" long) and mounted them UNDER the trailer frame. This combo seems to work perfectly. Total cost was about the same, but the Karavan kit has rollers and guides, a strudy mast stand, and clearance lights.
Since this trailer is a universal boat trailer (as is the Canai most probably) designed to carry up to 1250 lbs, the suspension was way too stiff for the light catamaran. So I simply removed the middle leaf from the spring and now it rides great.
Right now the Wave is still stored under a barn, so cannot take pics yet.
But I highly recommend this combo. The nice thing is, if I ever decide to get a Getaway, this trailer would work for it as well. Actually, if you want to see what this combo looks like with a Getaway, see this post w/ pictures from sail.fast24
